I have become a big fan of Mr. Zander's. The CD discussions of the symphonies are worth the price alone. He is clearly passionate about the music, as well as what's behind the music, delving into the composers life and perhaps Mahler's perspective. After listening to Zander's discussions and taking in his performance, it is quite interesting to go back to other versions I own and listen to them. Luckily, Mahler's genius is so great, that any well performed interpretation stands on it's own even if you disagree with certain aspects of it. Highly recommended.
